LOOSE LEAF s em Application filed June 20, 1929. "Serial No.372,248.

. This invention relates generally to loose leaf assemblies such asmemorandum pads, bridge-score cards and so forth.

One type of loose leaf assemblies consists essentially of a backingmember having posts and a pack of sheets resting on the backing memberand engaging the posts, the sheets being removable one by one withoutleaving a pack of stubs adjacent the posts. It will be appreciated that,when a fresh pack of sheets is placed in position on the posts andbacking member, said posts project but slightly above the pack ofsheets, but that, as the sheets are removed one by one, said posts willbecome more and more exposed thereby destroying the symmetry of thedevice and presenting an unsightly appearance.

The main object and-feature of this invention is the overcoming of theabove objection.

In the accompanying drawing the inven-. tion is disclosed in severalconcrete and preferred forms in which:

Fig. 1 is a top plan view of a device embodying the invention;

Fig. 2 is a vertical sectional view substantially on the plane of line2-2 of Fig. 1;

Fig. 3 is a vertical sectional view approximately at right angles tothat of Fig. 2 and substantially on the plane of line 3-3 of Fig. 1; andr v Fig. 4 is a fragmentary detail sectional view showing a modificationof the *invention.

1 indicates a backing member of any suitable construction, 2 are uprightposts and 3 denotes a pack of sheets supported by the backing member andengaging the posts.

at the point where they engage the post so arranged that an entire sheetmay be removed, that is to say: the sheet is not torn off so as to leavea stub. As the pack of sheets,

sheets diminishes the posts may be pressed of a thimble 12 having nearone end two The sheets are provided with perforations 4 relationthereto. -Various means may be employed for this purpose, but, in thepresent instance, they take the following form: Hol-. low legs 5 areassociated with hollow clampmg means. In Figs. 1 to 3 inclusive eachofthe hollow clamping means consists of a thimble 6, having ahead 7,externally threaded but passing freely through the backing member, and alocking nut 8. In the form here shown the threaded thimbleextends farenough down'to receive internally threaded portion 9 ofhollow leg 5.Each of posts 2 consists of a tubular member having a slit 10 to admitof slight expansion to frictionally' hold it in the backing member orthe devices carried thereby. It will now be understood that when a newpack of 'sheetsis placed in position posts 2 will be in an upper posi- Vtlon and that as the heightof the pack of downwardly so that theywill'not protrude unduly. r

In Fig. 4is shown a'modification of the hollow clamping means, whichhere consists spaced-apart flanges '13 and 14 between which the backingmember is clamped. In this instance, hollow sheet metal leg 15 isfriction ally carried on the thimble below the backing member and istherefore provided with a slit 16 similar to slitlOin the upright posts.

The advantages of this invention are that the device always presents aneat appearance, that an inclined writing surface is obtained, that theunused portion of theposts is nested within supportingmeans, and finallythat all adjustments are made with a minimum of effort.

1 is a on the posts to keep the sheets alined; and the particularlooseleaf assembly here shown, except the telescoping feature, is fully setforth and explained in Patent No. 1,569,528 ofMay-15,'19,28. I
